It's now 27 days since Sunspot region 3664 lobbed the CMEs that produced the great aurora show on May 10.
In 27 days, the Sunspot has undergone one full rotation and region 3664, now renamed as 3697, is back in a similar position as May 10. Although the sunspot region is still quite active - it generated an M6.1 flare today, but no CME - it seems to have thankfully lost some of its punch. No major CMEs have been launched during this round.
